One important product group is projection lamps.
These lamps, for projectors, measuring devices, microscopes, optical devices and other special applications have a high luminous flux and high light density.
On account of the heavy burdens and because the most important aspects of these lamps are the high luminous flux and high light density the life of these lamps is limited. So that the lamps perform at maximum capacity during their lives, they are manufactured with high precision and above all adapted exactly to the purpose they are intended for.
